Sorry, Fif. Thought you might be able to see this one. It's a little film of a tuxie, who is speaking in French with English subtitles about how depressing it is that his people keep taking him to the vet to pronounce him healthy - and to look for gunk in his ears.

Wesley refers to Bobby as the little lemon cat, so that's why he chose "citron" as opposed to "chamois." I suppose if Henri, who is not really ALL "noir" can be le chat noir, then Robert can be "citron."
